This book is a great help if you are thinking about buying a property. Now or at a later date.
It is irrelevant what purpose the purchase is intended to serve, ie whether you want to live in the property yourself, rent it out, or simply invest your money in tangible assets.
Most real estate buyers, who are not yet experienced, are afraid. Scared of the unknown, but above all - scared of losing money. Perhaps you still feel insecure dealing with all the experts of the different institutions.
